为自由形态的表面结构的实现的一个必要步骤是创造一有效结构系结那满足不仅建筑上的美学，而且结构的表演。作为力量的表示采用主要压力轨道流动在自由形态的表面上，一条自动格子产生途径为建筑上的设计被建议。算法自动地在 3D 上阴谋主要压力轨道自由形态的表面，并且采用协调的修改进展前面产生结构的格子的技术。基于建议算法，一个自动格子发电机说出 St-Surmesh 为自由形态的表面结构的实际建筑上的设计被开发。在为博览会上海 2010 的博览会轴的阳光山谷之一的表面几何学为验证建议途径作为一个数字例子被选择。比较研究被执行表明不同结构的格子怎么影响自由形态的表面结构的设计。

英文摘要：

An essential step for the realization of free-form surface structures is to create an efficient structural gird that satisfies not only the architectural aesthetics, but also the structural performance. Employing the main stress trajectories as the representation of force flows on a free-form surface, an automatic grid generation approach is proposed for the architectural design. The algorithm automatically plots the main stress trajectories on a 3D free-form surface, and adopts a modified advancing front meshing technique to generate the structural grid. Based on the proposed algorithm, an automatic grid generator named ＂St-Surmesh＂ is developed for the practical architectural design of free-form surface structure. The surface geometry of one of the Sun Valleys in Expo Axis for the Expo Shanghai 2010 is selected as a numerical example for validating the proposed approach. Comparative studies are performed to demonstrate how different structural grids affect the design of a free-form surface structure.
